How do you find the radios and the height for this problem?

natita [175]

Answer:

radius=2, height=3

Step-by-step explanation:

diameter= 2x the radius therefore 4/2=2=radius

cylinder volume formula=πr^2h

volume=12π

height= v/πr^2=12π/π*2^2=12π/π*2^2=12π/4π=3

hope this helped!

Given f(x) = 52x, evaluate f-1), f(o), and K2).<br><br> 01/25, 1, 625

lbvjy [14]

Answer:

$f(-1) = \frac{5}{2}$

$f(0) = 5$

$f(2) = 20$

Step-by-step explanation:

Given

$f(x) = 5(2^x)$

Required

Determine f(-1); f(0) and f(2)

Solving f(-1)

In this case, we simply take x as;

$x = -1$

Substitute -1 for x in $f(x) = 5(2^x)$

$f(-1) = 5(2^{-1})$

Apply law of indices

$f(-1) = 5 * \frac{1}{2}$

$f(-1) = \frac{5}{2}$

Solving f(0)

In this case, we simply take x as;

$x = 0$

Substitute 0 for x in $f(x) = 5(2^x)$

$f(0) = 5(2^0)$

$f(0) = 5(1)$

$f(0) = 5$

Solving f(2)

In this case, we simply take x as;

$x = 2$

Substitute 2 for x in $f(x) = 5(2^x)$

$f(2) = 5(2^2)$

$f(2) = 5(4)$

$f(2) = 20$

6(2c+3d)=5(4c-3d) solve for d

Arturiano [62]

Answer:

d = $\frac{8c}{33}$

Step-by-step explanation:

6(2c + 3d) = 5(4c - 3d)

6(2c) + 6(3d) = 5(4c) - 5(3d) distribute out the terms

12c + 18d = 20c - 15d

18d + 15d = 20c - 12c get all like terms onto the same side

33d = 8c

d = $\frac{8c}{33}$ divide by 33 to isolate the d variable
